Definitions

  • the present invention relates to a system for measuring and dispensing solid dry flowable materials. More particularly, the present invention relates to apparatus for measuring and dispensing solid dry flowable agricultural products.
  • U.S. 5,029,624 discloses a closed granular chemical handling system comprising a dispensing valve and a receiving valve that are configured to operate in a desired sequence.
  • U.S. 4,054,784 discloses a weigh feeder system including a device for controllably discharging a substance from a container and apparatus for weighing the container.
  • WO95/10363 pertains to a metering device for dry direct injection into a spray tank.
  • the present invention provides a portable apparatus for measuring and dispensing solid dry flowable materials, comprising:
  • Fig. 1 is an illustration of the measuring and dispensing apparatus.
  • Fig. 2 is a side view of the measuring and dispensing apparatus.
  • Fig. 3 is a front view of the measuring and dispensing apparatus.
  • Fig. 4 is a schematic representation of a side view of one embodiment of the quantitative measuring device of the apparatus of the present invention.
  • Solid dry flowable materials of this invention are powders, granules, or in general, solid materials which are flowable.
  • Typical solid dry flowables can be, but are not limited to, agricultural products, pharmaceuticals, inorganic or organic pigments, plastics, cosmetics, foods like dehydrated dairy products, animal feeds and the like.
  • Product specific refers to a single product.
  • This invention is especially useful for providing a portable means to transfer low use rate agricultural products in a way that minimizes spillage, accurately measures and dispenses a specific product, provides minimum operator exposure to the product dispensed, improves recordkeeping, labeling and inventory control.
  • the measuring and dispensing system comprises a weather proof, lockable cabinet (10) within which is mounted housing (12). Within lockable cabinet (10) is on/off power strip (14) which controls electrical power to the system. Housing (12) contains the operating components of the system. Mounted in the upper portion of housing (12) is hopper (16) having inlet opening (18) and outlet opening (20). Hopper (16) is capable of containing a suitable amount of solid, dry flowable material and can be connected to and operated in cooperation with material inlet means (22). Hopper (16) is preferably made of a material that is resistant to corrosion and that has a relatively low coefficient of friction. In a preferred embodiment, the hopper can be sealed substantially air-tight.
  • hopper (16) will be mounted on top of, i.e., above, quantitative measuring device (26) of the present invention, and the material will be gravity fed to the material inlet means.
  • Alternative means for introducing material to material inlet means (22) and sealing the apparatus can be used without departing from the present invention.
  • material inlet means (22) Attached to the bottom of hopper (16) surrounding outlet opening (20) is material inlet means (22) shown here as an electronic shutoff valve but which can be a manual shutoff valve. Material inlet means (22) allows the material to flow out of hopper (16) and into quantitative measuring device (26). Material inlet means (22) is shown here equipped with interlock sensor (24) which ensures that material inlet means (22) is in the open position before dispense of material is initiated from hopper (16).
  • quantitative measuring device (26) mounted in housing (12) is quantitative measuring device (26) to receive receptacle (32) and ensure proper alignment under materialinletmeans (22).
  • the components of quantitative measuring device (26) are optionally mounted on a frame support (50) and device housing (52) for convenient access.
  • the quantitative measuring device (26) can comprise an exchangeable module.
  • One embodiment of quantitative measuring device (26) can measure the weight of material being dispensed into receptacle (32).
  • Another embodiment of quantitative measuring device can measure the volume of material being dispensed into receptacle (32) and is dependent upon the bulk density of the material.
  • An example of quantitative measuring device (26) for weight measurement is a 10K loadcell #MS4010 from measurement specialists of Palm Bay, Florida. Those skilled in the art will readily appreciate that other devices may be used.
  • Longitudinal screw housing (40) having a cylindrical cavity has positioned within it screw (42) having flights designed to measure, transport and reduce the size of the solid dry flowable material that enters screw housing (40) by means of material inlet means (22) which is adjacent to screw (42) at one end of screw housing (40) and exits screw housing (40) and enters receptacle (32) at the other end through dispensing outlet (28) and material outlet means (30).
  • Material inlet means (22) connects hopper (16) to screw housing (40) and admits material to a first portion of screw (42).
  • Material inlet means includes a port in screw housing (40) which is suitably at least the width of 1 flight and preferably at least 1.5 flights so that composition is preferably fed being to more than one screw-flight.
  • the port is also of a dimension and location such that preferably the particulate composition is always fed to a constant-depth portion of screw described hereinafter even when the longitudinal position of screw (42) is adjusted within screw housing (40), as described hereinafter.
  • Means (56) for adjusting the longitudinal position of screw (42) within screw housing (40) adjusts the position of the screw flights relative to material inlet means (22) and material outlet means (30) which are in fixed position on screw housing (40).
  • the amount of adjustment is limited so that material inlet means (22)will always feed to a constant-depth portion of screw flight.
  • Means (34) for rotating screw (42) relative to screw housing(40) shown here as drive motor (34) is preferably adjustable by system control means (36)so that rpm of screw (42) can be varied, and once adjusted it must hold constant so that a steady amount of material is transported from inlet to outlet and into receptacle (32).
  • Suitable means (34) includes a variable speed motor coupled to the screw shaft such that the motor has sufficient power to turn the screw at suitable rpm. Coupling of rotating means (34) to the shaft must be able to accommodate the longitudinal adjustment of screw (42).
  • Screw (42) is mounted within housing such that the ends of screw (42) or a shaft that is supporting screw (42) form a seal with the respective ends of screw housing (42) such that if material inlet means (22) and material outlet means (30) are also sealed, none of the material that may enter the cavity will be able to exit the cavity other than through material outlet means (30). Close tolerances between the shaft ends and the respective portions of screw housing (40) can provide a seal to prevent passage of any material other than through material outlet means (30).
  • seals (58) include standard lip seals (single, double or triple) or pressure sealing rings. Preferred are lip seals.
  • the constant depth portion of screw (42) is at the inlet end of screw (42), and flights with a tapered shaft become increasingly more shallow toward the outlet end.
  • the constant-depth flights are preferably at least as deep as the diameter of the largest particle of the material, and preferably at least three times as wide as the diameter of the largest particle.
  • the threads on screw (42) which form the flights can be any one of various shapes including triangular, square, rectangular, rounded or trapezoidal. Rectangular threads are preferred.
  • the longitudinal distance between the center of the threads parallel to the screw axis is known as the pitch. Feed rate will be determined by the pitch, the depth of the threads, the slope of the threads, the shape of the threads and the speed at which the screw is rotated.
  • the pitch chosen for screws useful in the apparatus of the present invention will preferably be from 0.1 to 3 per centimeter.
  • a pitch of about 1 thread per centimeter is generally preferred for agricultural compositions in which the active ingredient is a sulfonylurea or materials of similar potency, which are generally applied at rates of milligrams per square meter (ounces per acre).
  • a larger screw with a different screw configuration will be used to get the appropriate feed rate.
  • the shaft supporting screw (42) contains at least one groove (60) around the circumference of the shaft at a location on the shaft between the last screw flight at the outlet end of screw (42)and the seal formed between the outlet end of the shaft of the screw and the outlet end of screw housing (40), with the at least one groove (60) positioned on the shaft at a location adjacent to material outlet means (30).
  • Groove (60) around the circumference of the shaft at a position on shaft between the last screw flight at the outlet end and the seal formed between the outlet end of the screw shaft and the outlet end of the housing helps prevent the exiting particulate composition from being forced into the outlet end seal (58) instead of dropping freely through the outlet into receptacle (32).
  • Groove (60) is connected to the last flight, is at least as deep and wide as the last flight, and is smooth so as to avoid any points where solid composition might collect. Preferably groove (60) is deeper and wider than the last flight.
  • Screw housing (40) and screw (42) can be made of any hard, wear-resistant material.
  • screw housing is stainless steel and the screw is stainless steel or hardcoat anodized aluminum.
  • Other parts of the present apparatus can be made of stainless steel, plastic, plexiglass, wood or other non-rusting, non-corroding sturdy materials.
  • the system is first calibrated to ensure that an accuarate quantity of material is metered each time.
  • the material is loaded in the hopper and the hopper is preferably sealed.
  • the quantitative measuring device When the quantitative measuring device is activated, the material passes from the hopper, through material inlet means, into the quantitative measuring device and is forced toward the material outlet means.
  • adjustments to the number of turns of the screw controls the amount of material dispensed.
  • weight measurement controls the amount of material dispensed.
  • a user will enter an amount of product required (or alternatively, a rate and number of acres) on a weather proof keyboard and the device will meter the required the amount of product into receptacle (32).
  • receptacle (32) is placed under dispensing outlet (28) or material outlet means (30), if present, and material inlet means (22) is opened.
  • the desired amount is entered into system control means (36) using the numeric key pad (44).
  • the dispense cycle is initiated by pressing a start button which activates the quantitative measuring device (26) through system control means (36). Once the desired amount has been dispensed quantitative measuring device (26) shuts off automatically.
  • System control means (36) at material outlet means (22) is closed and receptacle (32) is removed.
  • the system control means (36) displays a request for a four digit Personal Identification Number (PIN). This number, which has been previously programmed into the system, controls access to the dispensing cycle of the system. Once the operator's PIN number has been entered using the numeric keypad (44), and accepted the display advances to the main operating screen. This screen provides access to the dispensing routine, a display of current hopper inventory and the update inventory routine. The update inventory routine is used when product is added to hopper (16).
  • PIN Personal Identification Number
  • Access to update inventory routine is protected by a second 4 digit PIN which can be different from the power up PIN and controls who has access to inventory updating.
  • a "Job Number” is requested. This "Job Number”, which is entered by the operator, provides unique identification for each batch dispensed.
  • the display prompts the operator to place an empty receptacle(32) on or beneath quantitative measuring device (26). The screen then displays the quantity requested and prompts the operator to press the "start” button to open material outlet means (30) and begin the actual dispense.
  • Product is then dispensed into receptacle (32) until the targeted amount minus a preset quantity is reached.
  • the system then goes into a dribble routine which dispenses very small individual batches of product into receptacle (32) until the exact targeted amount is reached.
  • the quantitative measuring and dispensing apparatus of this invention provides a convenient way to accurately measure and dispense solid dry flowable materials; in the case of agricultural materials the quantitative measuring and dispensing apparatus allows last minute changes to acreage or changes in product use rate; keeps records of product use and inventory; helps address worker exposure issues since the transfer of the product can be done in a closed system.
  • the field measuring and dispensing apparatus of this invention provides better accuracy (+/-2%) compared to hand-held measuring guide (+/-7%).
